I have a bit of an issue with my magick, I have only been practising for a month or two and the only spells that work for me are from the darker side of magick.

Also I have accidentally summoned 5 spirits/demons just by reading the spell in my head and whenever a friend of mine (who claims to be "born with magic") touches something of which I have cast a good luck charm on, I get really bad luck and I can't wear it again, no matter how many times we try to cleanse it or put another good luck charm on the item.

The spirits arent an issue as I have gotten rid of all them but it just keeps happening every now and then.

That must be really annoying and strange. First of all PLEASE try Sage your home! Use a protection spell too, try crushing up egg shells with protective herbs and burying it by your home or in a jar in your home. If the spirits bother you tell them to leave immediately, tell them no negative energies are allowed in or around your home. Also where you or your friend live many people could have died or something so they tend to roam there. If you can get your friend to meditate on positive energies and her chakras then great, tell her cleanse her home and objects as well as you. I hope this works! Mail me anytime you need help

I am very much doubting your ability to summon demons with no baseline knowledge of the craft.
Spells cast by beginners often have no result because they do not know the baseline information neeed to get a magickal result.

May I ask what kind of spells you are reading? Where are they from? etc...

It may simply be that there is no problem, especially if what you are casting is fake.

Your friend is also probably just as much "born with magic" as the rest of us, no one is a hereditary witch even if their parents practice, it is something that anyone can do if they want to learn. It may simply be that you are getting the opposite of what you put out, especially if you are new there is a chance of backlash with spells cast incorrectly, your friend may have nothing to do with the bad luck, it may simply be your spells.

If you don't protect yourself and you start messing around with it then possibly, yes, it's more likely to be dangerous if you don't know what you're doing or you don't take it seriously and you try dark magic. Light magic hardly ever becomes dangerous, if you mess it up it just doesn't work where as dark magic can backfire on you.

Hmm now i know why i had a curse After a spell i Tried to do. I had that curse for Almost Five years . But i did another spell to get rid of it. So its gone now and until then i have Been careful with magick .
